因此，OPERA团队使用了比上一次短3,000倍的质子脉冲来重复他们的实验，这样就会大大提高了中微子开始行驶时间的精确度。
Thus, the OPERA team repeated their experiment using proton pulses that were 3, 000 times briefer than last time, giving greater precision to the start time of neutrinos.
借助于10倍的像素，再加上数字信号固有的高精确度，图像具有不可思议的细节表现力和稳定性。
With 10 times more pixels on the screen, all displayed with digital precision, the picture is incredibly detailed and stable.
它的精确度是2008年较早类型精确时钟的两倍以上。它是由美国科罗拉多州博尔德(美国科罗拉多州中北部城市)的国家标准与技术研究院所研制成功的。
It is more than twice as precise as an earlier version, reported in 2008, and was built at the National Institute of Standards and Technology in Boulder, Colorado.
